I recently noticed a very slow drip from my boilers pressure relief value. When I say slow, I mean real slow (a couple drops per day).
Pressure is slightly high, but is consistent in the low 20s PSI (20-23 or so). PRV is set at 30 PSI max, which I have never seen the boiler get this high.
The boiler is only 4 yrs old.
Anything to be concerned about?
